Weight gain after gastric sleeve surgery is generally not an expected outcome. The primary goal of the surgery is to treat obesity and facilitate weight loss. In the post-operative period, individuals typically begin to lose weight.

However, weight gain after gastric sleeve surgery can rarely occur and is usually attributed to specific reasons. These reasons may include overeating, reverting to unhealthy eating habits, lack of exercise, non-compliance with the prescribed diet plan, or psychological factors.

While it is possible to gain weight after gastric sleeve surgery, adopting a healthy lifestyle is crucial to sustaining the effectiveness of the surgery and maintaining weight loss. This includes following a balanced and low-calorie diet, engaging in regular exercise, ensuring appropriate nutrient intake, cultivating healthy eating habits, and adopting a supportive psychological approach.

Adhering to the recommendations of the doctor and dietitian, attending regular check-ups, and seeking support when needed are important steps to prevent weight gain after surgery. The key is to adhere to post-operative lifestyle changes and maintain a healthy approach to weight management.
